Am I able to submit a filing and/or payment, required to be submitted on SEDAR+, directly to the securities regulatory authorities?

No, filings that are required to be submitted on SEDAR+ will not be accepted if filed in paper or using another delivery method outside of SEDAR+. Similarly, fees payable on SEDAR+, must be paid on SEDAR+ as other payment methods will not be accepted.

The only exception to the above is if you are relying on a temporary hardship exemption, in which case you will need to follow the process identified in NI 13-103.
